I have run into Morons from the time I worked at a Service Station during high school (over a $2 car wash) until the time I retired. Some of the deals involved tens of millions of dollars, but I always did everything I could to keep a Customer happy.

No matter if you are dealing with some lady that thinks her car is not clean enough or some small country you are buying tankers full of oil from I always tried to be the most helpful person out there. My fall-back line was always 'Well, I can see why you would think that' and usually I could, but I would do what I could to keep them as a customer.

As long as it did not turn into an everyday sort of thing I still made money over the long run. I also checked with them now and then to make sure they were making money on the deal as well.

If both sides are happy with a contract then it is a good one.
